of the hose to be secured is a significant factor.

Another object is to provide a Wire-clamping device that is compact,simple, and facile in use.

Still another object is to provide a wire-clamping device that can bemanipulated with one hand.

A further object is to provide a wire-clamping device comprising apistol-shaped clamp and a spring-loaded trigger feed thereon for thewire to be secured on a coupling.

Further objects and advantages of this invention, as well as itsconstruction, arrangement and operation, will be apparent from thefollowing description and claims in connection with the accompanyingdrawings, in which Fig. 1 is an end elevation of a wire-clamping deviceshowing a preferred embodiment of the invention;

Fig. 2. is a side elevation thereof, partly in section;

Fig. 3 is an end elevation of the nose portion thereof;

Fig. 4-. is a plan view of said nose portion;

Fig. 5 is an isometric view of a hose coupling showing a clamping wirepositioned thereon;

Fig. 6 is an isometric view of said hose coupling, showing another stepin the operation of the wire-clamping device, and showing a portion ofsaid device in phantom; and

Fig. 7 is an isometric view of said hose coupling showing a wire clampedthereon.

Similar numerals refer to similar parts throughout the several views.

The frame of the wire-clamping device comprises a hollow handle I l,which forms the stock or buttvof the pistol shape defined, and a hollowbarrel l3 integral with said handle and extending therefrom. Said barrelis preferably rectangular in cross-section, with the face distal saidhandle open, and terminates in a tapered nose I5 having a plurality oflocating holes I? positioned on opposed faces of said nose andcommunicating with the interior of said barrel, and having a transversegroove l9 in the tip of said nose, for the purposes hereinafterdescribed.

Fork 2! is carried slidably and non-rotatably in the portion of barrelI3 that is of uniform cross-section, said fork having a transverselyserrated or notched interior base 23 and opposed upstanding tines orears 25. Hollow screw 21, which is integral with fork 2|, extends beyondthe open end of said barrel distal said nose, said screw 21 beingslidable freely in said barrel. 0

Cam 29 is provided with a transversely toothed portion 31, said cambeing carried rotatably between ears 25 by means of pin 33. Said cam iscarried at such eccentricity that rotation of said cam by means ofintegral lever arm 35 in a clockwise direction, as shown in Fig. 2,decreases the distance between the toothed portion 3! of said cam andthe notched base 23 progressively, for the purposes hereinafterdescribed.

Disc 3'! is threaded on screw 21; retaining plate 39 is securedremovably to handle I l, with screw 2'! being slidable in a bore in saidplate, so that disc 31 is carried at a notch in said handle in suchmanner that displacement of said disc relative to the barrel it isprevented. Said disc is provided with a plurality of ratchet teeth 4|disposed radially on a face of said disc, and the rim of said disc isknurled to facilitate manual rotation.

A trigger is is mounted rotatably on pin 45, which is carried in boxesin opposite faces of handle II. A lug l! integral with said triggerextends through an arcuate slot 49 in one face of handle H,said slotbeing concentric the path of rotation of said trigger so that lug 41 isslidable therein. Pawl 5| is carried rotatably on lug 4! by means ofwasher 53, and compression spring 55 is secured between lug 41 and pawl5| to maintain clockwise tension on said pawl, as shown in Fig. 2.

Compression spring 51 is secured between trigger 43'and the base 59 ofhandle II to maintain clockwise tension on said trigger, as shown inFig. 2.

In operation, when it is desired to clamp a wire in such a manner as tocouple a hose 6| to a conduit 63 on which said hose is positioned, aclamping wire 65 is doubled upon itself and then bent around the hose 6!(passing preferably twice around said hose). The free ends of said wire65 are then passed through the loop formed by doubling said wire, asshown in Fig. 5.

The free ends of said wire 55 are then passed through a pair of holes I?(accessibility determining whether the pair of holes I! above or thepair below groove H3 is employed), then passed between the toothedportion 3| of cam 29 and the notched base 23 of fork 2|, and then passedinto the bore of screw 27, until suitable slack has been taken up toposition groove l9 upon the crest of the loop of wire 55. Lever arm 35is then rotated to clamp said wire securely between the toothed portionSi and the notched base 23.

When trigger 43 is squeezed, pawl 5| engages one of the ratchet teeth 4|and thereby rotates I disc 3'! through an angle of several degrees, thedistance of rotation being determined by the length of travel permittedlug E7 in slot 49. Upon release of the pressure exerted by the operatoron trigger 43, said trigger is restored to its orig- 1,

inal position by compression spring 57, while pawl 5| is moved intoengagement in the root of the next tooth of the ratchet wheel 4| by thetravel of its axis, lug M, in the slot 4 9 and by the rotative force ofspring 65.

It is thus seen that upon each stroke of pawl 5| and resultant rotationof disc 37, screw 27 and its integral fork 2| and cam 29 are fedrectilinearly away from the nose of barrel |3, thereby drawing the freeends of wire 55 into barrel l3 while the groove l9 retains the loopedend of said wire in selected position. It is thus apparent thatrepetition of this stroke a sufficient number of times is effective totighten wire 55 on hose 6|.

To cinch or clamp the wire 55, the wire-clamping device is rotated onthe axis of groove l9 back over the looped portion or standing part ofthe wire, preferably for an angular distance of more than 90. The disc37 can then be backed off a number of turns to relieve tension, pawl 5|being disengaged from ratchet teeth 4| by rotation counterclockwise, asshown in Fig. 2. Then lever arm 35 is rotated to release the grippingengagement of the wire 63 effected by the cam and fork, and thewire-clamping device removed from the wire. Excess wire can then be cutoff and the free ends of the wire 65 clinched upon the looped portion ofsaid wire, as shown in Fig. 7, by means of a rawhide mallet.

It is apparent that, in lieu of the trigger-actuated feed hereinabovedescribed, rapid take-41p of the wire can be effected by manual rotationof disc 3'1, thereby permitting speedy operation in applications whereaccessibility of the hose to be clamped is not a significant factor.

Various modifications and changes can be made in the subject devicewithout departing from the scope of the invention.

The invention described herein may be manufactured and used by or forthe Government of the United States of America for governmental purposeswithout the payment of any royalties thereon or therefor.
